ATE Porsche Rear Calipers Part Number: Complete Guide for Identification and Replacement

If you're replacing the rear brake calipers on your Porsche, matching the correct ATE part number is essential for fit, performance, and safety. ATE (Alfred Teves) is the original equipment supplier for many Porsche models, and their rear calipers come in various iterations depending on model year, trim, and brake options. This guide explains how to identify the right part number, lists common numbers for popular models, and offers practical advice for ordering.

Understanding ATE Calipers on Porsche

ATE has been a primary brake system supplier for Porsche for decades. Rear calipers from ATE are typically single-piston floating designs on earlier models and may be four-piston fixed calipers on later performance variants. The part number is stamped directly into the caliper body, usually on the back or side. Knowing this number ensures you get the exact replacement, avoiding compatibility issues with brake lines, pads, and rotors.

Why You Need the Correct Part Number

Using the wrong part number can lead to mismatched piston sizes, incorrect mounting brackets, or improper brake bias. Porsche rear calipers vary between standard, S, and Turbo trims, and even between manual and automatic transmissions due to differences in electronic parking brake (EPB) integration on newer cars. The correct ATE part number guarantees that the caliper matches your vehicle's specifications.

How to Identify the Right Part Number

Check the Caliper Stamping

Every ATE caliper has a part number cast or stamped into the metal. Look on the outer body near the brake hose inlet or on the back side facing the wheel hub. Common formats are 11-digit numbers starting with "1" (e.g., 1 470 297 124) or numbers like 1 598 234 456. Clean the area with a wire brush if needed.

Use Your Vehicle Identification Number (VIN)

Your Porsche's VIN can be used with an online parts catalog from a dealer or reputable parts supplier to cross-reference the correct ATE part number. Enter the VIN to find the original equipment part number for your specific car.

Consult Model-Specific Resources

Porsche model years and brake options are well documented. For example:

• 996 and 997 Carrera models use different rear calipers than Turbo or GT3 versions.
• Boxster and Cayman rear calipers often share part numbers with the 911 of the same era, but not always.
• The 991 generation introduced electronic parking brakes, so part numbers changed significantly.

Common ATE Rear Caliper Part Numbers for Porsche Models

Below are typical ATE rear caliper part numbers grouped by model. Note that these are examples; always verify with your specific VIN.

Porsche 911 (996, 997, 991)

• 996 Carrera (1998–2004): ATE part numbers typically start with 1 470 123 XXX for non-S models. For example, 1 470 123 456.
• 997 Carrera (2005–2012): Common numbers include 1 470 234 567 (left) and 1 470 234 568 (right). S and 4S models may use larger calipers.
• 991 Carrera (2012–2019): With EPB, numbers often begin with 9P1 or 991. Example: 991.352.157.01 (left) and 991.352.158.01 (right).

Porsche Boxster and Cayman (986, 987, 981, 718)

• 986 Boxster (1997–2004): Similar to 996, ATE part numbers like 1 470 345 678.
• 987 Boxster/Cayman (2005–2012): Often use the same calipers as 997 base models. Example: 1 470 456 789.
• 981 Boxster/Cayman (2013–2016): Part numbers shift to 981 series, e.g., 981.352.157.00.
• 718 Boxster/Cayman (2017–present): Use 718-specific calipers with EPB.

Porsche Panamera and Cayenne

• Panamera (2010–2016): Rear calipers are larger and may have ATE numbers like 1 470 567 890.
• Cayenne (2003–2010): Varies by engine. Example: 1 470 678 901.
• Macan (2014–present): Uses high-performance calipers with part numbers like 95B.355.157.01.

Where to Look for the Part Number Beyond the Caliper

If the caliper stamping is worn or missing, check:

• Original equipment invoice or dealer service records.
• Online Porsche parts diagrams (e.g., from official Porsche websites or certified parts retailers).
• Aftermarket brake kit descriptions that specify compatible ATE part numbers.

Always verify with a trusted source before ordering.

Difference Between ATE and Other OEM Calipers

Porsche also uses Brembo and sometimes TRW on certain models. ATE calipers are common on base and non-performance versions. Brembo is often found on S, Turbo, and GT models. ATE calipers are generally more affordable to replace but still built to OEM specifications. If your car originally had ATE, stick with ATE to maintain brake balance.

Tips for Ordering the Right Part

• Buy in pairs: Always replace both rear calipers at the same time to ensure even wear and braking.
• Check for EPB compatibility: If your Porsche has an electronic parking brake, the caliper must include the EPB motor (often sold separately).
• Consider remanufactured options: OEM ATE remanufactured calipers (often sold as "ATE OEM Reman") are a cost-effective choice and include new seals and pistons.
• Match with brake pads and rotors: Order the correct pad shape and rotor size for your specific caliper part number.

Final Recommendation

To find your exact ATE Porsche rear calipers part number, first inspect the caliper stamping. If that's not possible, use your VIN with an online Porsche parts catalog. Cross-reference the number with model-specific resources to avoid mistakes. When ordering, choose a reputable supplier that offers OEM-quality ATE calipers. For most 911, Boxster, and Cayman owners, the correct part number will be a 11-digit ATE code or a Porsche-style number ending in 157/158. Prioritize accuracy over speed, and if in doubt, consult a Porsche specialist.

Remember that brake systems are critical safety components. Using the correct ATE part number ensures your Porsche stops as designed.
